We selected CUE as the configuration language in Holos for a number of reasons described in this post. The process was a combination of process by elimination and the unique way CUE unifies configuration.

I'm excited to share Holos, a Go command line tool we developed to make it easier to manage a platform built on Kubernetes. Holos implements the rendered manifests pattern as a data pipeline to fully render manifests generated from Helm, Kustomize, or CUE in a holistic way.
